Definitions

  • the present invention relates to a machine tool for machining workpieces, having a stationary machine frame, having a tool spindle with a spindle receptacle for clamping a machining tool, and having a first slide guide with the aid of which the tool spindle can be moved in a first axial direction relative to the machine frame, further comprising a tool magazine having a plurality of magazine locations for holding a plurality of processing tools, wherein the tool magazine has at least one movement path along which the magazine locations run, and wherein the movement path defines a lateral surface within which the first slide guide is at least partially arranged ,
  • Such a machine tool is off DE 43 11 469 C1 known.
  • the known machine tool is a so-called traveling column machine.
  • the spindle head with the tool spindle hangs vertically on a so-called traveling column.
  • the tool spindle can be moved up and down on the traveling column in the vertical direction.
  • this direction of movement is referred to as Z-axis.
  • the traveling column is arranged on a so-called cross part, which allows a movement of the traveling column in two mutually orthogonal horizontal direction.
  • the first direction of movement is realized in that the traveling column is mounted on a first horizontal slide guide, which is arranged at the top of the cross member. This direction of movement is commonly referred to as Y-axis.
  • the second horizontal direction of movement results from the fact that the cross part is in turn mounted on a second horizontal slide guide. This is commonly referred to as the X-axis.
  • a tool magazine with a movable chain is guided around the outer periphery of the cross member and fixed to the cross member.
  • the chain magazine is carried along during the movements of the cross part on the second carriage guide.
  • a great advantage of this arrangement is that the tool magazine is integrated in a compact manner in the machine tool and therefore the known machine tool has a relatively small footprint.
  • this arrangement of the tool magazine allows the replacement and replacement of a machining tool in the so-called pick-up method.
  • the tool spindle stores a machining tool directly in a magazine place or picks it up directly from a magazine place.
  • a gripping element acting between the tool magazine and the tool spindle is not required in this method.
  • the known machine tool allows very fast tool change and thus very short chip-to-chip times.
  • a disadvantage of this known machine tool is that the number of magazine locations in the tool magazine is essentially determined by the size of the cross part. An enlargement of the tool magazine or an increase in the number of magazine slots is possible only to a limited extent by the circulating chain in the X or Y direction is extended. To clear one To provide larger magazine capacity, therefore, a separate, second tool magazine is usually required, which is arranged behind the known machine tool, wherein the processing tools are then relocated using a handling unit between the two tool magazines. The handling unit and the second tool magazine require additional control functions, which is why this type of increase in the number of magazine locations is relatively complex and expensive.
  • DE 39 30 071 A1 discloses a traveling column machine in which the tool magazine is designed to be interchangeable.
  • a plurality of tool magazines are arranged on a space-fixed frame within the travel range of the traveling column. Both on the traveling column and on the frame transfer devices for the exchange of tool magazines are provided.
  • the traveling column can remove a tool magazine from the separate frame in order to subsequently use it when machining a workpiece.
  • the used tool magazine is also carried along with the movements of the traveling column.
  • a machine tool in which a tool magazine is arranged laterally of the traveling column of the machine.
  • the tool magazine can be pivoted into the working area of the tool spindle and swung out of the working area.
  • a magazine chain for holding editing tools is guided laterally and above a (in this case typically lying) tool spindle.
  • the tool spindle moves outside of the magazine chain, which although can rotate on a suitable chain guide, but is not carried along during the movements of the tool spindle.
  • the trajectory includes in particular a (known per se) magazine chain.
  • the magazine locations can in principle also run along the movement path in other ways.
  • the magazine chain is movable and preferably arranged circumferentially, it is now seen as a whole stationary because the magazine chain (or more generally the trajectory) is no longer carried along in the movement of the tool spindle.
  • This arrangement has the advantage that the weight of the tool magazine during the process of the tool spindle does not have to be moved, which allows a higher dynamics and / or the use of lower-cost drives.
  • the size of the tool magazine or the number of magazine positions is no longer limited to a length which results essentially from the outer circumference of the cross member, as is the case with the machine tool described above.
  • the (chain) length and thus the number of magazine locations can in principle be increased as desired.
  • the new machine tool thus enables the integration of tool magazines with a larger number of magazine locations.
  • the number of magazine locations has been increased to 120.
  • the new machine tool benefits from the advantages that enable the integration of a trajectory.
  • the basic structure of the machine tool described above can be maintained. Increasing the number of magazine locations is possible without additional drives and associated control functions. Therefore, in preferred embodiments, the new machine tool can continue to perform tool changes in the pick-up process. As explained below with reference to preferred exemplary embodiments, a very compact machine construction is still possible. In fact, in preferred embodiments of the invention, the "footprint" is only marginally increased in comparison to the machine tool described at the outset, although the number of magazine places has been significantly increased.
  • the new machine tool therefore allows an increase in the number of magazine locations in a manner in which all the advantages of the machine tool described above are retained.
  • the machine tool has a second slide guide ("X-axis"), with the help of the tool spindle is movable in a second axial direction relative to the machine frame, wherein the second slide guide is at least partially disposed within the lateral surface.
  • the first and second slide guide are orthogonal to each other.
  • the first slide guide is arranged on the upper side of a cross member, which is movable on the second slide guide.
  • the lateral surface is a preferably circumferential, closed surface resulting from an imaginary projection of the trajectory or catenary perpendicular to the area enclosed by the trajectory or catenary.
  • the lateral surface thus encloses a spatial area which includes both the base area enclosed by the movement path and the spatial areas lying on both sides of this base area.
  • the lateral surface would have the shape of a circular cylinder.
  • the lateral surface accordingly has a different cylindrical shape.
  • the trajectory travels around both the first and second carriage guides, i. the tool spindle is moved in both directions (viewed in a vertical plan view) at least partially within the movement path. This embodiment allows a particularly compact design.
  • first and the second slide guide are arranged predominantly within the lateral surface.
  • first and the second slide guides lie completely within the envelope surface, i. the slide guides do not protrude beyond the lateral surface.
  • the trajectory substantially determines the lateral dimensions of the new machine tool with respect to a plane that is clamped parallel to the first and second carriage guides. This embodiment allows a maximum increase in magazine capacity.
  • the movement path defines a base area having a longitudinal extent and a transverse extent, wherein the first slide guide has a first length and the second slide guide has a second length, and wherein the first and second lengths approximately correspond to the longitudinal extent and transverse extent.
  • the enclosed by the trajectory base corresponds approximately to that area which is spanned by the first and second carriage guide.
  • This embodiment leads to a particularly compact design with a very efficient increase in magazine capacity.
  • the required space is only slightly larger compared to the machine tool described above. Nevertheless, in a preferred embodiment, the number of magazine locations could be increased to 120.
  • first and the second slide guide are arranged at a vertical distance from each other, wherein the movement path extends in the region of the vertical distance.
  • the trajectory extends in a plane which lies substantially between the planes which are spanned by the first and second carriage guide.
  • the new machine tool has a cross part, which moves within the area enclosed by the movement path. The trajectory lies approximately at the height of the cross section.
  • This design also contributes to a very compact design with increased magazine capacity.
  • this embodiment allows a cost-effective conversion of existing machines of the type described above, so that they can be equipped with larger magazines.
  • this configuration allows short travels of the tool spindle when changing tools in the pick-up process, which is advantageous for the reduction of the chip-to-chip times.
  • the movements of the tool change can be largely taken over by the machine tool described above.
  • first and the second carriage guide define two parallel planes, which lie above the movement path.
  • the new machine tool has a cross member which moves above the base surface, which is spanned by the movement path. Tool spindle and cross part are thus on the same side of the plane defined by the movement path surface.
  • This embodiment is particularly advantageous for very large machines that are designed for machining very large workpieces. In such machines very long carriage guides are needed. These can protrude over the lateral surface due to the preferred embodiment, without the movements of the tool spindle and the tool magazine are affected.
  • this embodiment enables the use of magazine chains whose length is less than the outer circumference around the first and second slide guides. The capacity of the tool magazine can therefore be scaled very easily, which allows a cost-effective implementation.
  • the movement path is a stationary guide which is firmly connected to the machine frame.
  • Such a guide makes it possible in particular to attach a magazine chain to a "conventional" machine frame, which allows a cost-effective implementation.
  • a chain guide allows a smooth and trouble-free chain run. The latter applies in particular when the chain guide supports the chain over the entire path.
  • the guide is designed to guide a flexible traction means, in particular a chain, in a horizontal plane, wherein the magazine locations are arranged on the traction means.
  • the new machine tool could also be realized with a trajectory and in particular with a magazine chain, which rotates in a vertical plane or a "tilted” plane.
  • a horizontally guided chain has the advantage that the chain without "sagging" evenly loaded, which allows a smooth, fast and trouble-free chain run.
  • the tool spindle is arranged vertically.
  • the tool spindle is arranged on a vertical traveling column, which is mounted on the first carriage guide.
  • the tool spindle could, for example, be arranged on a portal or a bridge. Even with such frame shapes, a vertically arranged tool spindle can be realized.
  • the use of a driving stand for arranging the tool spindle allows a particularly compact and stable construction.
  • the use of a vertically arranged spindle enables particularly simple and rapid tool changes in the pick-up process when the magazine chain rotates in a horizontal plane.
  • the tool spindle is designed to approach at least one of the magazine locations directly in order to remove or deposit a machining tool.
  • a tool change takes place in the pick-up process, which allows very fast tool change, a compact space and a relatively simple machine control.
  • the tool magazine has a plurality of movement paths, which are arranged one above the other.
  • the trajectories are largely congruent to each other, but with a certain skew offset, which allows a tool change in the pick-up process.
